One hundred dogs were placed with sheep producers in Idaho, Oregon, Washington, and Wyoming during summer 1987 through summer 1988 as part of the APHIS-ADC livestock guarding dog program. Mortality as of February 1990 from culling and accidents is 39% and was evenly split between the first and second year of life. The 60 dogs currently working were rated as follows: 78% good, 12% fair, and 10% poor. All dogs rated good or fair were judged to have reduced predation or helped to keep predation minimized. Success of the dogs was breed-related but did not differ between pasture and rangeland sheep operations. About 50% of the producers who participated in the program either have purchased or plan to purchase additional guarding dogs.
